I found HTTP/2 core in Arduino ESP32 core, but how should I adjust the esp_tls issue

[blaticslm]

My test server does not have any of the verification, but how can I adjust this issue? My code is down below. This is my first time in dealing with HTTP/2.

The current support for HTTP/2 is through the ESP-IDF and not from Arduino API. You can use the ESP-IDF APIs inside your Arduino code.

Here is a starting point: #1130 (comment)

The Arduino API for HTTP/2 will be implemented in a future release of the Arduino-ESP32 Core.
